After occupying this position for ten or twelve years, he was obliged to leave on account of ill health, consequent on the fever he had in Essex, which left him with a very debilitated constitution. Being recommended to take a sea voyage, he, on account of his young family, determined to emigrate, at first having his attention directed to Australia, particularly as a gentleman of some position in the botanical world, with whom he was well acquainted, had emigrated and settled there some two or three years previously; but finally he determined to come to America, intending to settle in Canada, having letters from Lord Bathurst, then Foreign Secretary, and other influential friends, recommending him to Sir Peregrine Maitlasd, then Governor of Upper Canada, and other distinguished gentlemen. It appears to have been his intention to have established himself in business there as a nurseryman; but upon his arrival in New York, in November, 1821, he was prevailed upon by Dr. Hosack and other gentlemen to whom he had letters of introduction, to settle in New York, notwithstanding that the letters that he had to Sir Peregrine Maitland contained instructions to grant him certain privileges, as to land, etc, should he desire to establish a nursery in Canada.

In the spring of 1822 he took a piece of ground situated where Twenty-third street and Broadway now meet, but then quite away from the city, and commenced business, the only nurseries then about New York being those of Messrs. Prince, at Flushing, and Floy & Wilson, of that city, the first only having any reputation for plants.

In establishing himself in business, he had many serious difficulties and disappointments to contend with, chiefly owing to the want of taste among the mass of the people. As an amusing instance of this, we will relate an incident which he often referred to as exemplifying the ignorance of the people in regard to plants. He had quite a stock of beautiful Pelargoniums, which were then just being broke from their native species into the beautiful varieties which we now have. Among them were Eclipse, Lady Washington, Waterloo, Commander in Chief, and other seedlings raised by himself which were quite renowned in their day. They were all coming into beautiful bloom, but no one came to buy or to admire, and he became quite despondent, when one afternoon Mr. Lang, editor of the New York Gazette, called on him, to whom he related his troubles. Mr. Lang recommended him to sell them at auction, as being the most likely way of calling attention to his nursery and of disposing of his plants. The suggestion was favorably received, and Mr. Hogg accordingly arranged with Mr. Hoffman, a noted auctioneer of the day, and a great friend to horticulture, to have a sale.

Mr. Hoffman was to have a sale of dry goods on a certain day, and directed Mr. Hogg to send him, the afternoon previous, a cart-toad of them. Mr. H., in the advertisement of his dry goods, announced as to be sold a certain number of "Pelargoniums - a new and beautiful article." The trade were all alive to know what it was, but all the explanation from Mr. H. was that they had better come and see and purchase. After the regular sale of dry goods, it was announced that the Pelargoniums would be sold in one of the upper lofts, which was then opened. There was a good deal of merriment at the joke which was played off, but the company entered into it with spirit, and the plants realized double what Mr. Hogg would have gladly sold them for. It being made known whence they came, brought great numbers of persons, in their morning and afternoon rides, to visit and purchase at the nursery.

Notwithstanding the difficulties which he encountered, he persevered, cheered and aided by his friends in England, receiving continually new plants from Mr. Kent, Mr.Barclay (of the firm of Barclay, Perkins, etc Co., the celebrated brewers), who had a remarkably choice and extensive collection of plants; Messrs. Loddlies, Bassington, & Bunney; Mr. Sabine, of the London Horticultural Society; McNab, of Edinburgh; Murray, of Glasgow, and others; and encouraged here by Dr. Hosack, Dr. Mitchell, De Witt Clinton, Cadwallader Colden, Wm. P. Van Ness, and others prominent in their day for their lore of natural history.

In return for the many favors he received from his transatlantic friends, he made frequent excursions into many parts of the country, collecting new and scarce plants and seeds, to send abroad These excursions added much to his knowledge of plants, familiarizing him with their habitats and modes of growth. So successful was he in these collecting tours, that when Don and afterwards Douglas were sent out here by the London Horticultural Society, they were especially recommended to his charge by the Society, and he frequently accompanied them in their excursions in the neighborhood of New York and Philadelphia. Many were the amusing anecdotes, with which he was enabled to amuse his friends, gathered in these excursions, at a time when railroads were scarcely known or heard of.

He was one of the earliest members of the New York Horticultural Society, and his name appears among the original applicants for its charter. During the more active part of his life he was a hard-working member of the society, contributing largely to the first exhibition that was ever held in New York, and for over twenty years was always on its Inspecting Committee and a member of its Council; and we find, by the records of the society, that in 1823 he received a special premium for the introduction of new and rare plants; and the records show that he frequently received a similar award. In that year we find that he exhibited, among other plants, Bignonia pan-durifoUa and grandiflora, Hemerocallis Japonica, Phormium tenax, and Kennedia coccinea. The records of 1824 are missing, but in 1825 he exhibited Amaryllis John-sonii, Cymbidium Chinensis, Cistus libinotus, Phlox divaricata and stolonifera Celsia linearis, Alyseum utriculatum, Lachenalia luteola, Cactus speciosus, Schizanthus por-rigens, and Penstemon digitalis. In 1826 he exhibited Erica ventricosa, pregnant, and conspieua; Passiflora ovata, racemosa, alba, and princeps; and Daphne cneorum.

In 1827, Dracaena Australia; Gamia spiralis; Acacia falcata, pulchella, conspicua, and suaveolens; Watsonia corymbosa; Moraea indiflora; Bignonia venusta; Ixia tricolor; Chelone barbata; Verbena multiflda; Coreopsis columnaris; Gonolobus lavis; Heli-opsis Iaevis; Ximinesia enceloides; Picnanthemum linearis; Helianthus atrorubens; and Erica tetralix. In 1828, Epacris grandiflora, Fumaria nobilis, Anthyllus barba Jovis, Begonia Evansii, and other plants.

In the earlier days of the society, there appears to have been a generous rivalry among the professional men, and the numbers of new plants presented in a season, by Floy, Wilson, Prince, Phelan, Parmentier, Mr. Hogg, and others, were, we think, greater than would be presented in the same time at the present day.

Among the numerous plants which he was the means of introducing into England, was Rhododendron arboreum; and into this country, Primula sinensis and Wistaria sinensis.

At different periods of his life he made different classes of plants specialities in his cultivation. In England he was noted for his cultivation of aquatics and tropical or hot-house plants; and he was among the first, if not the first, who successfully cultivated Nelumbium speciosum and Nymphaea caetrulea. In this country, he at one time devoted a great deal of attention to New Holland plants, and had a very large collection of them, such as Acacias, Banksias, Metrosideros, Eucalyptus, Melaleucas, &c; also with Pelargoniums, the new varieties of which, as already stated, he was the first to introduce into the country; and for a number of yean he imported, at considerable cost, the choicest varieties. To the Cactaceae, also, he at one time devoted much attention, and some ten years ago he had one of the choicest collections in the United States. Of later years, Orchids engrossed more of his attention. Of shrubs and herbaceous plants he was particularly fond; and these, with aquatics, always occupied a large share of his attention.

In his personal habits, Mr. Hogg was remarkable for the simplicity of his manners, his devotedneas to his profession, and the especial love he had for nature. Plants more particularly were the objects of his affection, if we may so speak He loved them for their own sake, and not for any lower motive. From early life a devoted Christian, always surrounded by those objects to which his tastes had caused him to devote himself, and with which he was, as it were, always communing, he troubled himself but little about the cares of the world. Leading a life of simplicity, without ambition, he pursued the even tenor of his way until he was suddenly called away, being stricken with cholera, which, although speedily arrested, so weakened him that his constitution, enfeebled by his advanced years, was unable to resist the shock it had received.
